Description

Technical Field

[0001] This utility model relates to the field of pipeline safety equipment, specifically an energy-saving and environmentally friendly natural gas flame-retardant device. Background Technology

[0002] Natural gas flame arresters, also known as fire suppressors, are used to prevent external flames from entering equipment or pipelines containing flammable or explosive gases, or to stop the spread of flames between equipment or pipelines. Flame arresters are designed and manufactured based on the principle that flames extinguish due to heat loss when passing through the narrow openings of a heat conductor. Using flame arresters ensures the stable operation of waste gas treatment systems, avoids production interruptions and environmental pollution caused by fires and explosions, and also reduces energy consumption and improves energy efficiency.

[0003] However, existing natural gas flame arresters still have the following problems during use:

[0004] Existing natural gas flame arresters use multiple heat conductor tubes as their flame arrestor cores. These tubes have a compact structure and can be installed using threaded rods and nuts, making installation and maintenance convenient. However, the flame generated by natural gas in the pipeline has a very high temperature, and the flow of natural gas in the pipeline is impactful, making the fasteners prone to loosening. This causes the flame arrestor core to shake within the flame arrester, lacking stability and affecting the safe use of the equipment. Therefore, it is necessary to develop an energy-saving and environmentally friendly natural gas flame arrestor device for use in the field of existing pipeline safety equipment. Utility Model Content

[0005] To address the shortcomings of existing technologies, the flame generated by natural gas in pipelines has a very high temperature, and the flow of natural gas in pipelines is impactful, making it easy for fasteners to loosen. This causes the flame arrestor core to shake within the flame arrestor, resulting in a lack of stability and affecting the safe use of the equipment. This utility model proposes an energy-saving and environmentally friendly natural gas flame arrestor device.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an energy-saving and environmentally friendly natural gas flame-retardant device, comprising:

[0007] The first cylinder, the second cylinder, and the sealing tube are provided. The sealing tube is symmetrically provided with assembly ring grooves, which are respectively engaged with the first cylinder and the second cylinder. Multiple first metal heat-conducting plates are fixedly assembled on the inner wall of the sealing tube, with the first metal heat-conducting plates near one end of the sealing tube. Multiple second metal heat-conducting plates are assembled on the inner wall of the sealing tube, with the second metal heat-conducting plates near the other end of the sealing tube. Assembly plates are fixedly assembled between the multiple first metal heat-conducting plates and between the multiple second metal heat-conducting plates, and each assembly plate is provided with an assembly groove.

[0008] The stabilizing mechanism includes support blocks and movable openings. The support blocks are fixedly mounted between two first metal heat-conducting plates and two second metal heat-conducting plates. The movable openings are all located on the assembly plate and between the two first metal heat-conducting plates and the two second metal heat-conducting plates, and are connected to the assembly groove.

[0010] Preferably, each of the traction blocks has an internal cavity, and each cavity is fixedly fitted with a telescopic spring. Each telescopic spring has an adjustment plate fixedly fitted to one end, and each adjustment plate has a telescopic button fixedly fitted to it. The telescopic buttons movably pass through the traction block, and each end of the telescopic button is inserted into one of the first and second locking holes. Multiple heat conductor tubes are assembled between the first and second metal heat conductor plates. The heat conductor tubes are located inside the sealing tube, and a connecting tube is fixedly fitted in the middle of the multiple heat conductor tubes.

[0011] Preferably, each of the connecting pipes has an assembly hole in the middle, and each of the two ends of the assembly hole has a positioning insertion hole located outside the assembly hole. Threaded rods are fitted onto the assembly hole on the connecting pipe and the mounting holes of the two assembly plates.

[0012] Preferably, the threaded rod is threaded with two operating nuts, which are respectively located in the mounting groove, with the first stop block located outside the operating nut and the second stop block located on one side of the threaded rod.

At this point, the first stop moves in the movable opening, fitting against the end face of the operating nut to restrict its movement. Simultaneously, the first stop moves the second stop on the extension block, fitting against the end face of the threaded rod to restrict its movement. This increases the stability of the heat conductor pipe and the connecting pipe on the sealing pipe. Attached Figure Description

[0037] In this utility model, the sealing pipe 30 is installed between the first cylinder 10 and the second cylinder 11 under the action of the fastening bolt 22 and the fastening nut 23. The flame generated by natural gas enters from the gas inlet pipe 12. The flame is extinguished due to heat loss when it passes through the narrow gap of the heat conductor pipe 40.

[0038] Working principle: The positioning hole 51 on the connecting pipe 41 is inserted into the positioning rod 61 in the first metal heat-conducting plate 32.

At this time, the mounting hole 60 on the assembly plate 52 and the assembly hole 50 on the connecting pipe 41 are connected. Threaded rods 42 are installed in the assembly hole 50 on the connecting pipe 41 and the mounting holes 60 of the two assembly plates 52. Operating nuts 43 are then installed on the threaded rods 42, each located in the assembly groove 53. The telescopic button 6209 in the first locking hole 6203 is pressed, causing the adjusting plate 6208 to retract the telescopic spring 6207, thereby causing the traction block 6205 to move on the traction cavity 6202 until the telescopic button 6209 is engaged with the second... When the locking hole 6204 engages, the first stop 6211 moves within the movable opening 6210. The first stop 6211 engages with the end face of the operating nut 43, restricting the movement of the operating nut 43. Simultaneously, the first stop 6211 drives the second stop 6213 on the extension block 6212 to move, causing the second stop 6213 to engage with the end face of the threaded rod 42, restricting the movement of the threaded rod 42. At this time, the stability of the heat conductor tube 40 and the connecting tube 41 on the sealing tube 30 increases. Under the action of the fastening bolt 22 and the fastening nut 23, the sealing tube 30 is installed between the first cylinder 10 and the second cylinder 11. The flame generated by natural gas enters through the gas inlet pipe 12. The flame is extinguished due to heat loss when it passes through the narrow opening of the heat conductor tube 40. The design is based on the principle that the flame is extinguished due to heat loss.
